Invasion Brandon Routh Superman Easter Egg
The end of tonight's episode saw the DC TV heroes celebrating, with Supergirl back to her Kara Danvers self. As she walks away, Ray Palmer (Brandon Routh) says she looks a lot like his cousin.
This is a nod to Brandon Routh playing Superman in 2006 with Superman Returns (as Superman and Supergirl are cousins).
Producer Marc Guggenheim offered the following to IGN about the Superman reference:

I’m like, ‘I’m getting it in one of these episodes.
